As you may be aware Gnome Shell requires 3d Acceleration, And although virtual box provided 3d acceleration, it does not currently work with Gnome Shell. As is documented here http://live.gnome.org/GnomeShell
Now you might say so what? who cares?
And if you did it would be because you failed to realize the implication of this over the next year.
When Gnome 3.0 is released it will come with Gnome Shell. Gnome Shell does not have a 2d fallback so if the 3d doesn't work then your stuffed.
So when Gnome 3.0 is released and picked up by all the major Linux distros, Virtual Box WILL NO LONGER WORK FOR ANY MAJOR LINUX DISTRO. Thats correct, in about a years time virtual box will have effectively stopped supporting all the major distros of Linux unless the 3d support is fixed.
Now with such a major problem on the horizon you would expect the Virtual Box forums to be buzzing with info on the problem and what is being done to fix it. But it seems completely silent on the issue, if fact I couldn't find anything about it at all on the main website, forum or bug tracker.
Does anyone know what if anything is being done to address this issue.
